[Heterogeneity of chromosomal abnormalities in cultured melanoma cells of human skin].

Karyotypes of 9 malignant melanoma patients has been described. It is ascertained that most often the damage is observed in chromosomes 1, 6, 7, 9 and 17, which is consistent with the data in the literature. Besides chromosomes 5 and 13 are also often involved in different rearrangements.

[A study of chromosomal fragility in peripheral blood lymphocytes in patients with lymphomas].

Patients with lymphomas were shown to have authentically a higher frequency of fragile sites, both spontaneous and induced by aphidikoline expression, in comparison with the control group. Differential sensitivity of chromosomes caused by the action of aphidikolin was revealed. The fragility of chromosomes 9 and 11 in patients with lymphomas on sites 9q31-32 and 11p13-14 was authentically higher (alpha = 0.

[Intracerebral hemorrhages with lesions of the extracranial portions of the carotid and vertebral arteries and arteries of the base of the brain].

The study deals with the clinico-anatomical examination of 75 cases of hemorrhagic strokes where diagnostical and therapeutical surgical measures were performed. Arterial hypertension was found in 73 cases. In 35 cases there were changes in the extra- and intracranial areas of the carotid and vertebral arteries and arteries of the brain basis.
